RE: TI-H: Okay I maybe overreacted
Could/would someone please tell me what transpires during a
link. I would be interested in any information from generic to
expert. Of special interest would be if it uses a proprietary
protocol, bit rate (baud), how handshaking is accomplished, etc.
Has anyone with a digital scope looked at it (I have only
analog).
Wow! I just thought of something after that last request. It
should be simple to log the data because (no brainier) you are
hooked to the parallel port. What I need then is to know what
the protocol expects for handshaking. Then I could write a quick
program to log the data. What puts the link into rx/Tx mode,
etc.
Thanks
